I’m building a REST web service with ASP.NET MVC 3. So i need to serialize this class in a XML and send it to the client. The problem is that i’m getting an annoying “d2p1” in every element of the XML. Here is an example of the response:

How do i get rid of the d2p1?

Answer 1

Qualify your DataContract with the “Namespace” Attribute, and then use the same namespace name.
Like this:

namespace PostIt
{
    [DataContract(Name = "ResultRequest", Namespace = "YourNamespace")]
    public class Result
    {
        [DataMember]
        Models.Core.Order order;
        [DataMember]
        int ErrorCode;
        [DataMember]
        String Message;
        ...
    }
    namespace Models.Core
    {
        [Serializable]
        [DataContract(Name = "Order", Namespace = "YourNamespace")]
        public partial class Order
        {
            ...
